How often should a concrete septic tank be pumped?
Most concrete septic tanks need to be pumped every 3–5 years, depending on household size, water use, and tank capacity. In coastal towns like Evans Head, where sandy soils and high water tables can affect system performance, sticking to this schedule is important. Regular pumping prevents solids from overflowing into the drain field, helping the system last longer and reducing the chance of costly repairs.
Can a septic tank work in coastal areas?
Yes, concrete septic tanks are well-suited to coastal conditions. Their weight and strength make them resistant to movement in sandy soils or high groundwater, which are common around Evans Head. Concrete also holds up well against corrosion, unlike some other materials. To keep the system effective, property owners should ensure the tank is properly sealed, regularly maintained, and installed by professionals familiar with coastal environments.
What size septic tank do I need?
The size of a septic tank depends on the number of people living in a home and daily water usage. A typical three-bedroom home usually requires a 3,000–5,000 litre tank, but larger homes or properties with high water use may need more capacity. For Evans Head properties, it’s important to choose a tank that not only suits household needs but also meets council and environmental requirements for wastewater management.
